Seeing Sound!

Concept:
• Project will create an entire light show on the
spot based on any sound input
• Prototype will take in an audio signal, from a
song to a person talking, and use LEDs to
make a matching light show
Motivation:
• iTunes and other music players make visual shows
to go along with songs, but these players only use
songs, and they have to look ahead in the song
due to a delay from the song to the visualization
• Our prototype will be able to create a light show
from any sound in real time

• Color Organ ($65)

– no intelligence
– only one color
• Christmas Tree Light Programmer ($500)
– All done by user
– done before hand
– not in real time
